Colin from Banks Bikes wants to test the effectiveness of a set of hydraulic brakes on a new Scott electric gravel bike for Drew, one of his favorite customers. Colin clamps the bike into the repair stand and rotates the pedals to start the rear wheel spinning from rest to its final angular velocity of 230 rpm in 5.3 seconds. a) Calculate the angular acceleration of the rear wheel in rad/s2? b) If Colin now slams on the bike's brakes, causing an angular deceleration of -88 rad/s2, how long does it take in seconds for the back wheel to stop spinning?
